Reliance Infra trading curbs: IRP-ASM rules 2026 explained

What triggered the latest focus on Reliance Infra

Reliance Infrastructure Ltd (NSE: RELINFRA) has again come into the spotlight after curbs on trading in its shares, linked to exchange surveillance rules applied to stocks tagged with insolvency-related status. The stock is otherwise described as actively and widely traded, with sustained investor participation and liquidity. But the current framework can sharply change how the stock trades, including when and how investors can take positions.

Market participants have linked the restrictions to the Insolvency and Bankruptcy Code (IBC) process and the Interim Resolution Professional (IRP) tag visible on exchange platforms. In the provided context, references to BSE’s website show the stock marked under “IBC IRP”, with the company stated to be in IRP stage-1.

Price action: lower circuit moves add to volatility concerns

Reliance Infrastructure (stock code 400868) saw sharp selling pressure on 6 Feb 2026, hitting a lower circuit at ₹119.73. The stock was down ₹6.3, or 5.0%, from the previous close, reflecting the maximum permissible daily decline for the day.

The move stood out against broader benchmarks mentioned in the context. The power sector declined by 0.3% while the Sensex fell 0.41%, indicating Reliance Infra’s fall was steeper than both the sector and the wider market on that day.

The pressure was not limited to a single session. Over the past two trading sessions, the stock was reported to have lost 9.75%, pointing to sustained selling and weak sentiment.

Why ASM matters: what the surveillance framework is meant to do

The stock is stated to be trading under the Additional Surveillance Measure (ASM) framework, which exchanges use to monitor stocks showing heightened volatility and unusual price moves. The context notes that ASM is a precautionary step meant to safeguard investor interests.

The lower circuit event itself reflects a market mechanism meant to curb panic selling and allow investors time to reassess positions. When a lower circuit is hit, trading can be automatically restricted, limiting further price discovery within that session.

In parallel, the ASM framework can tighten trading conditions via higher margins, restrictions on intraday activity, or other controls depending on the applicable stage and exchange rules.

Insolvency-linked tagging: the IRP stage-1 reference

A key factor highlighted is the IRP tagging associated with IBC proceedings. The context says the company is in IRP stage-1 and that this status is visible on BSE.

In the provided text, IRP is explained as the insolvency resolution process that begins under the IBC when a company is unable to meet obligations. Under IRP stage-1, exchanges can apply ASM-type restrictions that limit trading.

One description in the context states that in such a setup buying can be restricted while existing holders may be able to sell. It also mentions trading may be allowed only on a single day, typically Monday, which can compress liquidity into a narrow window.

Circulars and timing: what investors said changed abruptly

The context also refers to an investor-protection concern around timing and communication. It states that after the National Company Law Appellate Tribunal (NCLAT) stayed the insolvency proceedings on 4 June 2025, Reliance Infrastructure shares continued trading for months without disruption.

But later, BSE and NSE are said to have issued circulars dated 19 Dec 2025 that applied stricter IRP-linked restrictions. The text describes the implementation as sudden, with limited notice, and notes that the rules made “sell-only” trading mandatory on Mondays under ASM for IRP-tagged shares.

Ratings and risk flags: MarketsMojo downgrade details

The context includes a negative external assessment from MarketsMojo. The platform reportedly downgraded Reliance Infrastructure from “Sell” to “Strong Sell” on 5 Feb 2026, citing deteriorating fundamentals and heightened risk.

It also states the company’s Mojo Score stands at 26.0, described as signalling weak financial health and poor growth prospects relative to peers. The market cap grade is reported as 3, categorising the stock as small-cap with limited institutional interest and higher volatility.

Regulatory and enforcement overhang cited in reports

Separate from exchange surveillance, the text also mentions Enforcement Directorate (ED) actions linked to Anil Ambani-associated entities. It says the ED placed a ₹778.60 million lien on the company’s bank accounts for alleged violations under the Foreign Exchange Management Act, 1999.

It also mentions the ED attached seven properties of the company for alleged violations of the Prevention of Money Laundering Act, 2002. The agency is said to have attached assets worth ₹101 billion in a money-laundering case against Anil Ambani-linked companies, including assets worth ₹3.39 billion pertaining directly to Reliance Infrastructure.

What restrictions can mean for investors: margin and liquidity impact

One report excerpt in the context explains the practical impact if a stock is labelled as an investment warning: investors may need to pay 100% margin for purchases. This makes margin trading and credit-based buying impossible, and the report adds that alternate exchange transactions may also be blocked.

Combined with “sell-only” windows described for IRP-tagged stocks, these measures can sharply reduce the pool of buyers and worsen liquidity. This can amplify price gaps on allowed trading days, especially when investor sentiment is already weak.

Company calendar: board meeting for results

Reliance Infrastructure informed BSE that a meeting of its Board of Directors was scheduled on 31/01/2026 to consider and approve unaudited financial results (standalone and consolidated) for the quarter and nine months ended Dec 31, 2025.

For investors tracking the stock through a period of surveillance and insolvency-linked tags, scheduled disclosures can become key reference points, particularly when trading itself becomes restricted or intermittent.

Key facts snapshot

Why this episode matters for the power-sector stock universe

Reliance Infrastructure’s case shows how quickly trading conditions can change once a stock is placed under stricter surveillance and insolvency-linked tagging. Even where a stock is usually liquid, restrictions like limited trading days, “sell-only” rules, and higher margins can materially alter liquidity and price behaviour.

The context also notes steep longer-term declines: the stock has fallen nearly 40% over the past year and about 57% in the last six months, while another excerpt says it is down 45% over the past 52 weeks. Separately, a long-term comparison cited says the share price was ₹2,485 in 2008 and around ₹173.45 “today”, implying a fall of more than 93% over that period.

Conclusion

Reliance Infrastructure’s trading curbs, tied to the ASM framework and the IRP stage-1 tag under IBC-linked processes, have coincided with lower-circuit moves and sharp underperformance versus sector and benchmark indices. The next clear checkpoint mentioned in the context is the board meeting for unaudited results scheduled for 31/01/2026, while the stock continues to trade under tighter exchange conditions.
